Copy from existing model

This builder option performs a structure copy of the contents of an existing model to a newly defined model.

Step 1: Select an existing Relation model from the workspace using the browse button . Note: An existing model will be preselected if a Relational model in the workspace is selected in the VDB explorer prior to starting the new model wizard.

Step 2: If an exact copy of the existing model is wanted, ensure Copy entire model is selected. If all model entities should not be copied, select the Select Model Features to Copy option and use the tree to make your selections.

Transform from existing model

This builder is only applicable for creating a relational view model from a relational source model with the added feature of creating default transformations (SELECT * FROM SourceModel.Table_X) for each source table. The steps are the same as Copy Model From Existing Model described above.

Build XML documents from XML schema

This builder option performs a structure copy of the contents of an existing model to a newly defined model.

Step 1: Select an existing XML schema model from the workspace using the browse button . Note 1: An existing model will be preselected if an XSD model in the workspace is selected in the VDB explorer prior to starting the new model wizard. Note 2: The schema must be found in the workspace so if you need to get one or more into the workspace use the XSD Schemas on file system importer.

Step 2: Move the available schema root elements you want to become virtual documents in the new model over to the Virtual Documents list by using the arrow button for selected elements or the button to move all elements.

Step 3: Select the appropriate document options and mapping options.

Step 4: Click Finish to create a model of all selected document entities or use Next to view Selected Documents Statistics page which shows document entity statistics and gives you an idea the size of the model being created.

Step 5: (Optional) Click Finish to create a model of all selected document entities or use Next to view Preview Generated Documents page that allows you to exclude document entities.

Build from existing WSDL file(s) or URL
